The catch is that the FaceTime call must be started or scheduled by someone who has an iPhone with iOS 15 running on it or other Apple devices with the latest feature. As you may have guessed, this new accessibility of FaceTime definitely has a catch. If you think that the FaceTime app is coming on Android and Windows devices as well, that is not the case. With iOS 15, even people who don’t have Apple devices can talk over a FaceTime call on their device.
Previously, when you felt like calling a friend on FaceTime who did not have an iPhone or any other Apple device, your enthusiasm was bound to end in disappointment.
